You could be hearing an echo while using the audio-video feature of the Virtual Classroom because of the following reasons:
- The microphone is picking up sound from the speakers because microphone and speakers are not set up properly.
- If you hear your own audio back as echo, the problem is likely at the other end (attendee with audio controls). If other attendees are experiencing echo, then the echo is likely coming either from your side or any other attendee’s side (attendee with audio controls).
- You haven’t selected Reduce Echo option in Adobe Flash Player’s microphone settings.
Steps to eliminate echo
- If you are using an external microphone, keep it at least 10-12 inches away from your speakers. Try reducing the volume level of the microphone to 50% or turn off the microphone boost.
- Try using headphones, preferably a USB headset, instead of the usual speakers and microphone.
- Make sure that the Reduce Echo option in Adobe Flash Player’s microphone settings is selected. Refer to the steps below to select the Reduce Echo option.
If you are in the live class, simply right-click on the Whiteboard and click Settings (see Figure 1).
- If you face the echo issue while you are in the live class, simply right-click on the Whiteboard and click Settings (see Figure 1).
- Adobe Flash Player Settings window opens (see Figure 2). Click the microphone icon in this window.
- Select the check-box with Reduce Echo mentioned beside it (see Figure 3). Finally, click Close.
However, if you are not in a live class, you can visit www.wiziq.com/info/technical-requirement.aspx, and right-click anywhere on the gray area under Test Devices, and then click Settings (see Figure 4).
The Adobe Flash Player Settings window opens (see Figure 5). Click the microphone icon in this window.
Select the check-box with Reduce Echo mentioned beside it (see Figure 6). Finally, click Close. Be sure to save your settings by clicking the Save Settings button.
Whether you are using the browser-based Classroom or the WizIQ Desktop App to conduct your live class, it’s a good idea to use an external microphone, which helps reduce or eliminate echo. In addition, you need to ensure that the attendees who attend your class using tablet devices use a headset for audio communication. Not using a headset can result in echo.
